What's This?

Waaaaay, way overdue, I apologise ;___;

I've been meaning to draw Jack Skellington for absolutely ages, but every time I tried it just ended up not looking quite right :/
But now, the time has come, and I think I nailed it
Decided on Christmas Town for the background, thanks to everyone who commented on the preview.

Oh and there's an Easter Egg again! Can you spot it?

Done in Prismacolor Pencils on card, just under A4 in size.
